Actress Katie Holmes once again sparked rumours of dating actor Jamie Foxx after the two were spotted spending time together during Super Bowl weekend here.

Holmes, 35, and Foxx, 46, have reportedly been seeing each other since last summer and also spent time together at his mansion in California recently, reports nypost.com.

They are keeping their relationship under wraps out of respect for Holmes' ex-husband Tom Cruise, a source said.

Another source said that they are being careful because Cruise is a friend of Foxx. The two actors featured in the 2004 crime thriller 'Collateral'.

Cruise and Holmes parted ways in July 2012 after about six years of marriage.

Holmes and Foxx were first romantically linked after they were spotted dancing together at Ron Perelman's Apollo theatre in the Hamptons gala in August last year. However both strongly denied the rumours that time.
